Cigarette butts (CB) and cigarette butt fibers (CBF) are highly abundant and frequent residues on beach sand. Also, they are hazardous waste due to their significant toxicity and potential risk to the ecosystems' biota and the health of beach tourists. This study aimed to determine the abundance and density of CB and CBF found on the active, rest, and service zones of five pilot beaches in Argentina, Colombia, Brazil, Ecuador, and Mexico. The methodology involved collecting CB and CBF in 500 m transects of urban tourist beaches using a citizen science-adapted methodology between June 2021 and May 2022, during the COVID-19 pandemic. The abundance and density of CB and CBF, and the Cigarette Butt Pollution Index (CBPI) were calculated. The highest proportion of CB was found in service and rest areas. Bocagrande (CO) reported the highest generation of CB and CBF and a severe CBPI.
烟头（CB）和烟头纤维（CBF）在沙滩沙中大量且频繁存在，由于其具有显著的毒性和对生态系统生物区系以及海滩游客健康的潜在风险，因此它们属于危险废物。本研究旨在确定在阿根廷、哥伦比亚、巴西、厄瓜多尔和墨西哥的五个试点海滩的活动区、休息区和服务区发现的 CB 和 CBF 的丰度和密度。该方法涉及在 2021 年 6 月至 2022 年 5 月期间，在 COVID-19 大流行期间，使用适应公民科学的方法，在 500 米长的城市旅游海滩上收集 CB 和 CBF。计算了 CB 和 CBF 的丰度和密度，以及烟头污染指数（CBPI）。在服务区和休息区发现了最高比例的 CB。Bocagrande（CO）报告了最高的 CB 和 CBF 生成量和严重的 CBPI。
